Well, despite all the chaos everyone went through after GeoHot suddenly appeared in the jailbreak scene the Chronic Dev Team has finally released GreenPois0n to public after they have implemented GeoHot’s / Limera1n exploit into the Greenpois0n Jailbreak tool .

You can use it to jailbreak iOS 4.1 on iPhone 4, iPhone 3GS, iPod touch 4G / 3G and iPad. Support for iPod touch 2G and Apple TV will be added soon.

Here is a detailed Greenpois0n Tutorial on how to Jailbreak iOS 4.1 iPhone 4, 3GS, iPod touch 4G, iPad with this tool.

Update your iPhone and / or iPod Touch to iOS 4.1 and if you are Jailbreaking your iPad you will have to update your iPad to the iOS 3.2.2 before you can jailbreak your device.

NOTE TO UNLOCKERS!!!: If you rely on your current unlock, do not update to iOS 4.1 because if you do you will upgrade your Baseband / Modem Firmware as well, making it impossible for now to unlock.
